"House of pane: Apple was warned of glass danger" ["Apple declined to comment. But in January, Dan Whisenhunt, an Apple vice president of real estate and development, told the Rotary Club of Cupertino that birds flying into the glass had not proved much of a problem. 'Now, the humans on the inside, that's a different story,' Whisenhunt said. 'We've had people bump into the glass. That's a problem we are working on right now.'"] San Francisco Chronicle 3/2
